My construction involves I a -.star-shaped Anotherjfeature of my invention comprises.

l a body'structure with a multiplicity of sides from which. the somewhat conical glasses extend, these glasses-being molded to the proper shape and held in place by metal clips so that 1 their axes are in a position substantially radial to the center of an electriclight bulb mounted in the casing br'hou'sing.

utilize a 12-sided housingor casin structure and in which an electric lamp soc et is con nected'to the upper side. There are fivesides inclined upwardly, each having pyramidal or conical-shaped glasses. There are also five sides inclined somewhat downwardly, each having afglass pyramidal structure staggered in relation to the upper side: A single pyramidal glass structure depends from the bottom side of the casing or housing. This cas ing is divided in any suitable manner so that. access may be had to the interior to install or replace the lamp: .L

. In constructing my invention 12 and a lower section 13, these having an irregularjunction line 14 with a hinge 15 connecting-them'together. This housing is illustrated ashaving twelve sides and each side 'forming a 5-sided figure. r y A'lamp socket 16 is secured in an opening 17 in the top of the housing; and an electric 1; form a metal housing 11 which ha's'an-upper section lamp, preferably of. a spherical type, is i mounted in the socket inside the housing. The housing, as above mentioned, has the hinge 15 or any other type of hinge, .and is secured together in any suitable manner. In the particular form of my invention I Glasses 18 may be transparent or translucent andmay be molded in a-variety of shapes. The shape. illustrated is somewhat pyramidal having. five sides 19; and-each of these sides is somewhat fluted asindicated at. 20,

portion 22, and are preferably hollow in the lower portion 23. A flange 24 is formed integral with the glasses at their lower edge and above this flange there is a slight rim 25. The flange has a series of grooves 26 formed therein extending in a longitudinal direction.

I Each of the. sides of the housing has an opening 27 formed with five sides; and on each side'there is a clip or finger 28. The edge of the opening fits against the fiat portion 29of the glasses and the flange 24 of the'glasses fits inside of the structure of the housing so that the olips'or fingers 28 may ex tend inwardly through the grooves 26 and have'their inner ends. bent over as indicated 4 -'glass on the five sides.

It is obviousthat a'nyothertype o f'casing or housing may be utilized to contain the electric lamp, and that the glasses may be secured inposition in any desired manner. It

. is my 'idal glasses 18 intention, however, that the glasses be completely molded 0r shaped in the desired pyramidal or conical shape, and that therefore when the light is transmitted through the glasses there is no obstruction formed by leaded corners or the like.

It is also apparentthat if desired 'the glasses may be made solid or hollow as illustrated; and they may be made of thin mate rial having therequisite strength and in any desired colors.

Afeature of my invention is that the pyramhave 'wallsof different thicknesses as illustrated by the construction of" Fig. 8 and also there is a hollow or concave portion 20' forming a type of fiuting. This causes the glasses to act in a prismatic manner, giving a dispersion to the light projected therethrough from the lamp mounted in the center of the fixture. This therefore gives a pleasing effect.

" Various changes may be made in the principles of my invention without departing plurality of grooves, and a plurality of bent nation a multi-sided lamp housing,

' shaped ger clipsfl engaging 3. A lighting fixture comprising in combination a multisided lamp housing, most of the sides having an opening, a pyramidalshaped molded glass fitted in each 0 ening,

each glass having a flange, and a p urality of bent finger clips engaging each flange and holding each glass in position. s

4. A lightingfixture Tcomprising in combination a multi-sided lamp housing, most' of the sides having an opening, a pyramidalmolded glass fitted in each 0 ening and each of the glasses having walls 0 vary ing thicknesses giving a prismatic effect to the light transmitted therethroug 5. A lighting fixture comprising in combimost of the sides having an opening, apyramidalshaped molded glass fitted in each opening,

each glass having a flange, a plurality of bent finger clips engaging each flange to hold each glass in position, each glass having walls of varying thickness, whereby a prismatic effect is given by light transmitted from a lamp located centrally in the housing.

6. A lightin fixture having in combinationa multi-sided lamp housing, each side having a framing with five sides and an opena pyramidal-shaped glass fixture having a lamp-hou s the said grooves and. .holding the glass in position.

ing in the framing, a pyramidal-shaped glass mounted in each of the framings, said housing being formed in two sections separable along an irregular line'formed by the sides of the different framings, the housing being divided into substantially two equal parts.

7. A lighting fixture comprisingm combinationa multi-sided lamp housing, each side having five: edges, the edges being common to the other sides, most of the sides being'open' and having a five sided pyramidal glass fitted therein, the housing being divided into two substantially equal parts on an irregular line following the junction edge of a number of the sides. 5

In testimony whereof I have signed' my name to this specification.
